Roller pin screening and distinguishing device

Abstract

The invention relates to a roller pin screening and distinguishing device which comprises a base and a fixing frame. The base is fixedly connected with the fixing frame. Supporting pillars are fixedlyconnected to the upper end of the base, and the inner surfaces of the lower ends of the supporting pillars are fixedly connected with reset springs. Adjusting pillars are fixedly connected to the upper ends of the springs, and the upper ends of the adjusting pillars are fixedly connected with a discharging plate. A first screening plate, a second screening plate and a third screening plate are movably installed in the fixing frame, and the first screening plate, the second screening plate and the third screening plate are fixedly connected through connecting supports. By means of the roller pin screening and distinguishing device, due to screening holes with different hole diameters in the multiple sets of screening plates, roller pins with different diameters can be distinguished, the roller pin screening speed is increased, meanwhile, self adjustment of the discharging speed of roller pins is achieved, the stacking phenomenon of the roller pins is avoided, and screening can be fastand stable.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a needle roller screening and distinguishing device. Background technique [0002] Bearings are used in various types of mechanical equipment every year. Needle rollers are the main components of bearings, which directly affect the quality of bearings. Generally, bearings have a high speed during operation. If the needle rollers Unqualified thickness and precision or mixed needles can easily cause damage to the equipment, causing a large amount of economic losses in the slightest, and threatening the personal safety of the operator in the worst case. [0003] Therefore, needle roller manufacturers have high requirements for the thickness and precision of needle rollers. Screening out unqualified needle rollers is an indispensable process in needle roller production.

[0002] Bearings are used in various types of mechanical equipment every year. Needle rollers are the main components of bearings, which directly affect the quality of bearings. Generally, bearings have a high speed during operation. If the needle rollers Unqualified thickness and precision or mixed needles can easily cause equipment damage, ranging from bringing a lot of economic losses, to threatening the personal safety of operators

[0003] Therefore, needle roller manufacturers have high requirements for the thickness and precision of needle rollers. Screening out unqualified needle rollers is an indispensable process in needle roller production. Traditional needle roller thickness screening devices usually screen needle rollers in batches , the amount of needle rollers for each screening is small, and the needle rollers cannot be classified and screened in detail during the screening process, and the preparation time for each screening is long, and the efficiency is very low
